Specification forming part of Letters Patent No. 196,938, dated'November 6, 1877; application led J une 16, 1877.

To all whomV it 'may concern.'

Be it known that I, SVEN RYDBECK, of Red Wing, in the 'county of Goodhue and State of by declare that the following is a full, clear,

and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon..

Figure l of the drawings is a representation of a top View of my invention. Fig. 2 is aside view thereof. Fig. 3 is a cross-sectional view. Fig. et is a longitudinalcentral vertical section; and Figs l5, 6, 7,' and 8 are detail views. I I,

This invention has relationto improvements in corn-planters; and it consists in certain novel means whereby the platform carrying the dropper mechanism and the wheel actuating said mechanism are raised from the ground in turning at the end of a row or in driving from or tov a field; and it also consists in a seed-bonhaving a circular rabbet, a central bearing, a curved slot, and a dropopening, in combination with a disk having a spindle, a spur, a drop-opening, a reciprocating slide, and a transverse slot adapted to receive said spur, and in'the arrangement and novel construction of the various supplemental devices, as will be hereinafter more fully described.

In the annexed drawings, the letter A designates the platform of myimproved riding double-row corn-planter, having at each side a strong metallic bar, B, pivoted at its front end to the side-.beams of the platform, and

extended to the rear to afford bearings for the shaft C of two broad-treaded transportingwheels, D. Bars B also project rearwardly beyond the wheel, and are turned outward, as shown at a, thus forming Scrapers, which prevent undue accumulation of earth upon the tread of the wheels. The shaft C is extended through a wooden tree, A', upon which are rigidly secured, in any suitable manner, two spaced `metallic sectors, E, having edge flanges b, and, intermediate thereto, aAstrong recurvate hook, c. 4The under side of the platform is provided with two longitud- `inal ribs, upon which are rigidly secured angular metallic plates d, to the lower end of which is rigidly, but movably7 secured one end of an open-link chain, F. This chain passes around the sectors between flanges b, and engages the hookv c, aforesaid.

' F represents a lever rigidly secured to the tree A,and extending up therefrom within reach of the driver upon the seat G. It is provided with a spring-actuated latch, d', that engages the end of a rearwardly-projecting beam, e, upon the platform. When this lever is thrust to the rear, the tree A rotatesv upon the sh aft O, and the chains F are Wound around the sectors, thereby raising the platform bodily upward, and causing the runners G1 and the drivin g-wheel G2 to clear the ground, when the machine maybe turned or driven to any desired point. In this position the end of the catch d engages the beam e aforesaid, and holds the platform in the raised position. The runners G1 are provided upon their inner faces with horizontal guard-plates el, that prevent them from burying too far in soft soil, and at their heels with openers c2, that form the 4furrows into which the corn is dropped from the spout H, in rear of said openers. The rearwall fv of the spout is pivoted to the side walls thereof, about midway of its length, for the purpose of opening and closing the lower end thereof at the proper moment, and its upper end is engaged in an oblique slot, i, in a transverse slide, H', arranged in ways upon theplatform in 4front of the 'transporting-wheels. This slide is caused to reciprocate by means of a driving-wheel, G2, applied upon a transverse shaft, I, under the slide-board f, having a number of spaced cams, g', that engage the adjacent end of said slide in succession. lThe backward movement of the latter is had through a disk, J having a number of cams, g', alternating with those on the hub of the driving-Wheel, applied upon the remaining end of the shaft I, and rotating therewith. The reciprocation of the slide opens and closes the dropper-spout alternately and at the properinterval. The bottom w of the grain-boxes is provided with a circular rabbet, j, having a central openin g, k, in which is journaled a central spindle, j', upon a disk, K, and a lateral Acurved opening, s, throughwhich a spur, l, upon OFFfl'C.

said disk engagesa transverse slot, t, in ,said I Slide. .It has, also, a third opening; w', abovee-the spout, that, at each reciprooation of the slide, is brought into line with a perforation, n, in the disk. This latter osclates horizontally in its seat Ain thebox, and constitutes the pocket, by means of which a planting of corn is segregated from the mass in the V 'boxes' At each oscillatorgr movement .of

disk the pocket u passes under a fixed striker, L, secured to the stationary part of the bottom, and .any excess of grain for .a hill is effectually prevented. In lien of the camadisk i J, above described, l may app15r a second driving-Wheel, if I so elect, Without changing the .of my invention. f The driY-eIJS ,seat .above mentioned is formed on en inelieed rearwardly-.extending board,

M, hinged to the rear edge of the platform;

and .Silglported from the .axle by ineens .of a prop, having a shoe, m, bearing `upon a' rounded portion, o, of .said axle.- .By 'this ineens the drivers Weight is 'entirely removed from the vertically-.adjustable platform to the .axle of the meehine, .and in .raising the .sa-111e eoniparatively little eort is required.-

In .order to -eneee the .rows equally l .have

devised the following -markem It eonsists n .of` ,a beam., P, having .et end e iloveiverlilyfnrojeoting finger, p, .that is eirenged .et the front .end of the platform .et right .en gies .to .its length. This beam extends through .eoentrel guide, a, info wliieh it is .connefl 'by .e suitable pin, and, when extended .to either side j of the platform, .is received in an open guide,

q', at each lateral .edge thereof, that holds the beam in proper position for aecurately laying oft' the rv'vs. This marker is manipulated by means of arope secured at each end to the extremities of the beam.

What I claim Las new, and desireto secure l. The combination, with the platform A, pivoted i arms B, and the shaft C journaled therein, of the sleeve or tree A on axle C, the sectors E, having a peripheral groove, and a hook, e., a lever, Ff, and chains F, secured at ,one end to the pIatform, .passing around the sectors, and engaging with the hook, substantially asspecied. i

2 The Seed-box having aeircularrabbet j,

drop-opening,.w, in eombinationwith .a disk, l, having a spindle, j., a spur, l, and a dropopening, n, ,and a-reoiproeating-slide having e transverse slot, t, .adapted .to reeevesaid Spur, substantially as specified. i.

VThe .drivers Seat Gr., hinged. to the rear a central bearing, k, a .curved slot., s, .an a

end of the veitieally-.adjnstable platformA.,

overhanging" the axle, and provided with a Drop bearing thereon, substantially as and for .the purpose specified.-

In testimony thet eloim the above :I have hereunto `s libscrirbed ,my name in the presence of two witnesses..
